Touch not working on i.MX6 Android Dual display

[kirangv]

Hello,

I am working on "iMX6Q SABRE-AI" running "Android Marshmallow" with dual display(HDMI and LVDS).

I wanted to show different contents of HDMI and LVDS and I am able to do with the help of patch received from NXP.

Link : Dual display on imx6 android 

But when different contents are shown(using WindowManager API) , I am loosing the "touch" feature in HDMI and I need to use a mouse to work.

If same content is shown on both displays then this issue is not present.

Any Suggestions ?

Hello Kiran,

Would you mind to elaborate or make a video showing the issue?

Hi Diego,

Thank you for the help.

Later I will try to share the video , since i don't have the platform ready now.

Just for your information , i did applied a patch received from NXP for showing different contents on multiple displays.

From that patch i was not able to apply one lib change - please refer this thread Dual display on imx6 android.

Screenshot below :

May be this is causing the touch issue , am not sure ?

If i can get the modified lib (hwcomposer_fsl_imx6.so), then i can try and reply.

Thanks,

Kiran

I had received Triple Display application from NXP and in that application also touch is not working.

Can any one provide help on this ?
